High-voltage expertise for the next generation of vehicles
EVs and hybrids need specialist knowledge most workshops simply don’t have. We diagnose and repair high-voltage batteries, charging systems, inverters and hybrid drive components at OEM level β safely and correctly. Mobile service across all of Auckland.
Understanding why it matters β and why high-voltage work isn’t a DIY job
EV and hybrid specialist services cover the diagnosis and repair of high-voltage batteries, inverters, charging systems and hybrid drive components. It’s specialist work that requires HV safety training, OEM-level tools, and an understanding of systems most traditional mechanics never encounter.
Most workshops aren’t equipped β or trained β to safely work on high-voltage systems. Without proper isolation procedures and OEM diagnostic tools, HV battery and inverter faults are often left undiagnosed, or the vehicle is simply sent to the dealer at a premium price.
Our HV-trained technicians use OEM-level tools to safely diagnose, repair and recalibrate every part of your EV or hybrid’s high-voltage system β done correctly and safely, every time.

FAQ
FREQUENTLY ASKED QUESTIONS.
Everything you need to know about our EV & hybrid specialist services
What are the signs my EV or hybrid needs specialist attention?
Common signs include reduced range, slow or failed charging, a battery or HV warning light, reduced power, unusual noises from the drive motor, or error messages on the dash. If you notice any of these, it’s best to get it diagnosed before the issue worsens.
Is it safe to work on a high-voltage EV or hybrid battery?
Yes β when carried out by trained technicians using proper isolation and safety procedures, which is exactly how we operate. High-voltage systems require specialist handling, and our technicians are trained specifically for this.
Do you come to my home or office?
Yes β 100% mobile service. We bring our full OEM EV/hybrid diagnostic equipment to your home, workplace, or roadside location anywhere in Auckland. You don’t need to tow your vehicle. We work around your schedule, 7 days a week from 9am to 6pm.
How long does an EV or hybrid diagnosis or repair take?
A diagnostic scan typically takes 45 minutes to 1 hour. Repair time depends on the fault β a charging module or sensor repair can often be done same-day, while battery work may take longer. We’ll always give you a time estimate when booking.
Will you tell me before carrying out an expensive repair?
Always. We diagnose first, explain exactly what’s wrong and quote the repair before any work begins. You decide how to proceed β no surprise charges.
Can a battery fault be fixed without replacing the whole battery pack?
Often, yes. Many HV battery issues come down to a single faulty cell, module, or BMS fault rather than the entire pack failing. We’ll always diagnose the actual cause rather than assuming the worst.
Do you check battery health before buying a used EV or hybrid?
Yes. Our pre-purchase HV battery check gives you an independent state-of-health (SOH) assessment before you buy β so you know the real condition of the battery, not just what the dash says.
Is Afterpay available for EV & hybrid services?
Yes β Afterpay is accepted for all services. We also accept bank transfer. WINZ quotes are available upon request.
STILL HAVE QUESTIONS?
Our technician is happy to answer any questions before you book. Call, WhatsApp or email us β we’ll get back to you fast, 7 days a week.
